The 6.30mm pitch gives each circuit enough spacing for the.093" (2.36mm) diameter pin and socket contacts this series is named after — sized for 20-14 AWG wire in moderate-current applications.
Critical Procurement Note: Contacts Are Separate
This is a common pattern in the Commercial.093" series: the housing and the terminal are line items on the BOM. For the male pin and female socket contacts, look to the TE 770014 and 770015 series respectively. The crimp termination means the wire is attached to the contact before insertion into the housing, which keeps the assembly process straightforward for a harness shop.
